In this paper, we propose a single-step Deep Neural Network (DNN) for CE, termed Iterative Sequential DNN (ISDNN), inspired by recent developments in data detection algorithms. ISDNN is a DNN based on the projected gradient descent algorithm for CE problems, with the iterative iterations transforming into a DNN using the deep unfolding method.

The study analyzes images that have been cultivated by ancient cultural memories to become Korean cultural symbols, such as the model of women, the space containing the sediments of the times, and the way of life in daily activities and beliefs as a model of practice. Through that, the research wants to clarify the two major functions of these cultural symbols: shaping the national cultural identity and becoming a measure of valuation for contemporary perceptions of human dignity.
